IMAGING: MRI improves cost and accuracy of prostate cancer biopsy

Abstract

Randomized trials of screening for localized prostate cancer on the basis of crude PSA thresholds and 6-12-core template biopsies had disappointing results. To improve patient outcomes, novel diagnostic tools with a high discriminative ability for clinically significant cancer are needed. The use of MRI can improve detection at biopsy without disproportionate increases in costs.
